Well, I would first check the references given in the Help file!.
That's what they're for, no? Hastie's book is likely to more complete
on the algebra, I think.
You might also be interested in the relevant chapters of Friedman,
Hastie, et. al "The Elements of Statistical Learning Theory," which
might be a gentler exposition of the math.
Of course, the code (or a suitable exposition of it, which may not
exist) is the ultimate reference.
